WHAT'S FOLLOWING THE ISS? Several readers have reported seeing a "mysterious satellite" following the International Space Station. It trails the station by about one minute, relatively faint, but definitely there. Mystery solved: The follower is Progress 33, a Russian supply ship. On July 12th, it will come within meters of the ISS to test a new automated docking system. Check the Simple Satellite Tracker for flyby times--and get two spaceships for the price of one.

SUBSIDING SUNSPOT: Sunspot 1024 is experiencing some decay and solar flare activity is subsiding. Nevertheless, by recent standards it is still a behemoth. "Now approaching the western limb, the region provides a tremendous richness of detail through amateur solar telescopes," says Pete Lawrence who sends this picture from his backyard observatory in Selsey UK:

Many readers are writing to ask if this sunspot is going to produce a major solar storm today, July 7th. Such a storm was "predicted" by a set of crop circles in England, and the solar blogosphere has been abuzz with speculation. The answer is "no." A major storm is not in the offing. Sunspot 1024 is relatively large, but it does not have the kind of complex magnetic field that poses a threat for major eruptions. Crop circles, it turns out, are not a useful tool for forecasting solar activity.

FULL MOON: Tonight's full Moon is more than just a source of light and beauty. It also makes a good footrest:

Greek photographer P.Nikolakakos took the picture from a Spartan beach on July 7th. "I used an off-the-shelf Canon 40D," he says. After the model's feet were sufficiently rested, she bent down and cradled the Moon in her hands. "The Moon offers so many good photo-ops if only you are ready to take advantage of them."

Potentially Hazardous Asteroids (PHAs) are space rocks larger than approximately 100m that can come closer to Earth than 0.05 AU. None of the known PHAs is on a collision course with our planet, although astronomers are finding new ones all the time.
